K2 - Safe I/O Extension Card with Digital Inputs
With a voltage range of 24 V up to 110 V conforming to EN 50155, the K2 as an I/O card within the MTCS Modular Train Control System can be immediately used for railway applications.
The safe, SIL-4-certifiable card offers 16 binary inputs supported by extensive supervision functions and FSoE communication (Fail Safe over Ethernet) within the system.
The usage of vibration-resistant spring cage terminal blocks on the front facilitates a low wiring outlay and enables fast installation. The pulsed input of 1 to 10 mA protects the contacts from wetting voltages and therefore wear-related failures.
The MTCS family consists of the MH50C controller unit together with the safe, SIL 4-certified CPU board F75P and up to 6 I/O cards.
